We demonstrate that pro-inflammatory and anti-inflammatory cytokines communicate with distinct populations of vagal neurons to inform the brain of an emerging inflammatory response.
Where do you think those cytokines that are influencing the nervous system come from? White blood cells. That’s where it all starts, not the nervous system. You’re putting the cart before the horse.
Chemogenetic activation of the cNST neurons during an immune response suppresses inflammation.
The study you linked demonstrates the brain suppresses inflammation/fever, not promotes it.
